Technical Specifications

The SSL0804T-681M-N has an inductance value of 680μH. The 'M' indicates a tolerance of ±20%. It's crucial to consult the datasheet for the saturation current (Isat), which is the DC current at which the inductance drops by a specified percentage (e.g., 10% or 20%). The RMS current (Irms) represents the maximum continuous current the inductor can handle without exceeding its temperature rating. The operating temperature range typically spans from -40°C to +125°C. The 'N' suffix likely denotes the termination or packaging type. The shielded construction is achieved through a magnetic core material that surrounds the inductor coil, effectively containing the magnetic field and minimizing EMI radiation.

This inductor is frequently employed in buck, boost, and buck-boost converters to efficiently convert voltage levels. The inductor stores energy during the on-time of the switching element and releases it during the off-time, smoothing the output voltage. The low EMI characteristic is particularly important in applications where electromagnetic compatibility is critical, such as in automotive electronics, medical devices, and aerospace equipment. Furthermore, its small size makes it suitable for use in portable and space-constrained applications.
